In my co-'pending application, Serial No. 222,122, led on even date herewith, I have shown, described and claimed a wrist-watch case having portions thereof Vconstructed and arranged to form terminal-hoods within which the ends of a wrist-strap are anchored by meansI of strap-end anchoring-members which are permanently connected to or integrally formed lwith. the said wrist-watch case or terminal-hoods thereof. Ac-

cording to the above-identified application, in some instances, the strap-ends are positioned and anchored in the terminal-hoods of one of the case-forming parts prior to the assembly of :the said case-forming parts; in other instances, the strap-ends are introduced into and anchored Within the terminal-compartments either before or after the assembly of the case-forming parts; and in all instances, the actual positioning and anchoring of the strap-ends, is accomplished independently of the assembling of the said caseforming parts.

In the present application is shown, described and claimed, a wrist-watch case comprising: inner and outer case-forming parts; one of which is provided with strap-end anchoring-members which are permanently connected to or integrally formed with one or" the said case-forming parts; and the other of which case-forming parts is provided with permanently-connected or integrallyformed retention-members of Wall-portions which are constructed and arranged to effect the positioning and anchoring of the ends of a Wriststrap by means of or during the progress of the assembling of the said case-forming parts.

In the above-identified co-pending application as well as in the present application, the construction and relative arrangement of the parts in the lcompletely-assembled Wrist-watch case, operate to securely retain or lock the strap-ends in their anchored relation to the strap-end anchoringmembers.

In each of the several embodiments of the present invention herein shown, described and claimed, the Wrist-watch case comprises two oppositely-extending end-portionswith respect to a medial transverse plane and in the said endportions, the construction, relative arrangement and functioning of the parts is substantially similar. In consequence, a description of one end of the wrist-watch case in each embodiment of the invention, will in the main serve for both.

Referring to the embodiment of the invention shown in Figs. 1 to 6 inclusive, a watch-movement 25 is mounted in a Watch-receiving compartment 26 (Fig. 3) formed within and intermediately of the ends of a wrist-Watch case comprising an outer or front casing-part designated-'generally by the reference character 21 and an inner or back casing-part designated generally by the reference character 28.

As shown particularly well in Fig. 5, the inner casing-part comprises a bottom-wall 29 which constitutes the bottom-wall of the intermediate Watch receiving compartment 2B; laterallyspaced side-walls 30; and end-Walls 3| 3| which separate the intermediate compartment 28 from oppositely-arranged terminal-compartments to be presently referred to.

The outer casing-part 21, as is shown particularly well in Fig. 4, comprises a top-wall portion 32 having a sight-opening 32a and forming the top-Wall of the intermediate watch-receiving compartment 26; laterally-spaced side-walls 33--33 a pair of laterally-spaced end-Wall panels 34-34 at each end, with the space between the individuals of each pair of end-Wall panels closed by the adjacent one of the two oppositely-arranged terminal-hoods designated generally by the reference characters v35--35, and of less height, width and depth than the watch-receiving compartment 26.

Each of the end-Walls 3|-3I of the inner casing-part 28, forms with the adjacent one of the oppositely-arranged terminal-hoods 35-35, a

terminal-compartment 36 for accommodating one anchored end of a wrist-strap. Each end of the said strap will for convenience of description be termed a strap-end and is designated by the reference character 31. Each strap-end 31 is provided With a transverse slot 38 by means of which it may be anchored in the manner hereinafter pointed out. Each terminal-hood 35 comprises an arcuate. top-wall portion 39; a vertical terminal-end-wall portion 40 provided with a strap-receiving slot 4 i and laterally-spaced sidewall panels 42-42 which join the adjacent end- Wall panels 34-34 of the casing-part 21.

Permanently connected to each of the endwalls 3I--3l of the inner casing-part 28, is a strap-end anchoring-tong ue 43 which, in the form shown, is preferably formed as an integral extension of the upper portion of the adjacent endwall 3i and comprises a curved upper portion 43a substantially conforming to the inner surface of the arcuate top-wall portion 39 of the adjacent terminal-hood 35, and a depending portion 44 which latter, in the assembled positions of the outer and inner casing-parts, extends through the transverse slot 38 in the adjacent one of the strap-ends 31-31.

According to this embodiment of the invention, a strap-end 31 may be passed through a given one of the terminal-slots 4 |-4I in the respective end-Walls of the terminal-hoods 35-35 and anchored to the depending portion 44 of the adjacent anchoring-tongue 43 either before or after the inner casing-part 28 has been placed within the outer casing-part 21. It will be understood that the casing-members 21 and 28 may be retained in assembled position each with respect to the other by close frictional contacts between intertting portions of the respective casingparts.

In the embodied form of the invention shown in Figs. 'l to l0 inclusive, the outer casing-part which is generally designated by the reference character 45, is generally similar in construction to the outer casing-part 21 described above except for the modied form of the strap-end receivingopening in the terminal-wall of the hood-forming portion thereof to be presently described.

At each of its opposite ends, the said outer casing-part 45 comprises a terminal-hood generally designated by the reference character 46 and provided with a vertical wall-portion 41 having a clearance-notch 48 formed therein of sunlcient width to receive the strap-end 49 of a wriststrap.

Fitting within the outer casing-part 45 is an inner casing-part designated generally by the reference character 50 and comprising: a bottomwall portion laterally-spaced side-wall portions 52-52; end-Wall portions 53-53; and, at each end thereof, a bottom-plate extension 54 provided with an outer end-portion 55 at right angles thereto. The outer end-portion 55 of each extension 54 is provided with a central notch 56 of less width than the strap-end 49. The said strap-end 49 being provided with a pair of oppositely-arranged coupling-notches 51-51 in its lateral edges and respectively receiving laterallyspaced coupling-lugs 58-58 formed in the outerend portion 55 of the extension 54 by the notch 56.

According to this embodiment of the invention (Figs. 1 to 10 inclusive), each of the extensions 54-54 of the inner casing-part 5E! forms a closed bottom-wall for the adjacent terminal-compartment 59, the construction and arrangement of the said outer end-portion 55 being such that whenthe casing-parts 45 andSUfare assembled, the said outer end-portion 55 is caused to slidably engage the inner surface of the vertical end-wall 41 of theadjacent .terminal-hood 46. Before assembling the casing-parts v45 and 50,'a'given strapend 49 may be in a given clearance-notch 48 formed in the .end-Wall 41 of terminal-hood 46 with the coupling-notchesk 51-51 of the strap-end just within the inner surface of the end-wall 41, or said strap-end may be iirst anchored to the laterally-spaced lugs .58-58 on the extension 54 of the inner lcasing-part D in `such a Way `that when the inner casing-part 50 is placed within the outer casing-part 45, :the .strap-end 49 is anchored to the outer end-portion 55 of extension 54 and securely interlocked between the said outer end-portion 55 and the end-wall 41 vof the terminal-hood 46.

It will be understood from the foregoing that the terminal-compartment 55 at each end of the wrist-Watch case, is separated from an intermediate watch-receiving compartment 66 by an end-wall 53 of the inner casing-part 55.

According tothe embodiment of the invention shown in Figs. 1l to 14 inclusive, an outer casingpart, which `is similar in construction to the outer casing-part 21 shown in Figs. l, 3 and 4, is designated generally .by the reference character 6I.

For less exi- 'lpensive forms of wrist-Watch cases, the pyram- 5attached to the wrist-watch case, a series of anchoring-sockets or -recesses 16, shapedy and arranged to interlt with the pyramidal anchoring-points 68, are formed therein. When a given strap-end -69 is positioned within either one of two strap-receiving slots 1|-1I respectively formed in the kopposite vertical end-Wall portions 12-12 -of a pair of oppositely-projecting terminal-hoods designated generally by the reference characters 13-13, the subsequent introduction thereinto of the anchoring-points 68 will eiect a lateral as well as a longitudinal registration of the strap-ends within a terminal-compartment 14, one of which latter is formed in each of the terminal-hoods 13-13. The said terminal-compartments 14-14 are respectively separated from an intermediate watch-receiving compartment 15 by one of the end-walls 65 of the inner casing-part.

It will Abe understood from the foregoing that according to the embodiment of the invention shown in Figs. 1l to 14 inclusive, before the casing-parts 6I and 62 are assembled, a given strap-end 69 is approximately positioned in the strap-receiving slot 1| with the contracted upper ends of .the anchoring-sockets therein substantially in registry with the inner surface of the terminal-hood 13. The inner casing-part 62 is then moved upwardly into position Within the outer casing-part 6l to enter the anchoringpoints 68 into the anchoring-sockets 15 and thus lock the given strap-end 69 in place.

It will be understood that after the outer and inner casing-parts 6I and 62 have been assembled as described, the said casing-parts may be retained in assembled relation by their close frictional engagement.

According to the embodied form of the invention shown in Figs. 15, 16 and 17, the wrist-watch case comprises an outer casing-part designated generally by the reference character 16 and inner casing-part designated generally by the reierence character 11.
